Dinosaurs Grew to Outpace Their Young National Geographic Society/Corbis A newborn titanosaur had to get 2,500 times bigger before it reached adulthood. Some dinosaurs grew to gigantic sizes to avoid competition from their own young, rather than to take advantage of abundant oxygen, high temperatures and large territorial ranges, say two studies. But their largeness may also have proved their undoing. Some have argued that dinosaurs were able to grow quickly and fuel large bodies when temperatures were warm, oxygen levels were high, and land masses such as the supercontinent Gondwana provided abundant living space. But although the idea that certain environmental conditions favoured the growth of enormous dinosaurs has been popular among palaeontologists, there is little evidence for it. Friendly environment The team used thigh-bone lengths to work out the body sizes of more than 400 species alive during the Permian, Triassic and Jurassic periods (299 million to 145 million years ago).

List of common misconceptions From Wikipedia, the free encyclopedia This incomplete list is not intended to be exhaustive. This list corrects erroneous beliefs that are currently widely held about notable topics. Each misconception and the corresponding facts have been discussed in published literature. Note that each entry is formatted as a correction; the misconceptions themselves are implied rather than stated. Arts and culture Food and cooking Roll-style Western sushi. Searing meat does not "seal in" moisture, and in fact may actually cause meat to lose moisture. Legislation and crime Literature The Harry Potter books, though they have broken children's book publishing records, have not led to an increase in reading among children or adults, nor slowed the ongoing overall decline in book purchases by Americans, and children who did read the Harry Potter books were not more likely to go on to read more outside of the fantasy and mystery genres.

Fallacy List 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. A recent study revealed that the number of reported cases of STDs (sexually transmitted diseases) was significantly higher for high schools that offered courses in sex education than for high schools that did not. 2. SWEEPING GENERALIZATION: (dicto simpliciter) assumes that what is true of the whole will also be true of the part, or that what is true in most instances will be true in all instances. example: Muffin must be rich or have rich parents, because she belongs to ZXQ, and ZXQ is the richest sorority on campus. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life.
Metaphilm ::: Donnie Darko A new theory to help the viewer unravel the cult classic. Erik A. Coburn n recent years, Donnie Darko, directed by Richard Kelly, has become a cult classic. Explaining the timeline This diagram summarizes Donnie’s travel, to and from the Tangent Universe, to and from the past and the future. The entire movie occurs between points B and C on the timeline, aside from the last five or ten minutes, which happen at point A. Before getting into the explanations, there are some phrases that need to be defined: With these terms in mind, we can now begin breaking down the timeline. At point A, the Tangent Universe appears. He’s been here before Take a deep breath, now. Now what does this mean? What is Frank’s story? Frank is not a supernatural being. But, if Donnie is saved by Frank at the beginning, what about his first trip through the Tangent Universe? In every other attempt, Donnie shoots Frank before starting over. The Ensurance Trap He finally succeeds. Tying up the loose ends Wake Up Notes 1.

Personal and Historical Perspectives of Hans Bethe Invictus Knight's tour An open knight's tour of a chessboard An animation of a knight's tour on a 5 by 5 board. A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square only once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is closed, otherwise it is open. The exact number of open tours on an 8x8 chessboard is still unknown. The knight's tour problem is the mathematical problem of finding a knight's tour. Theory Knight's graph showing all possible paths for a knight's tour on a standard 8×8 chessboard. The knight's tour problem is an instance of the more general Hamiltonian path problem in graph theory. History The Knight's Tour as solved by The Turk, a chess-playing machine hoax. The earliest known reference to the Knight's Tour problem dates back to the 9th century AD. से ना ली ली ली ना ना ना ली ली ना ना ना ना ली ली ली ली where
